Abstract
There is disclosed a pressure swing adsorption process which permits recovery of oxygen at high purity levels from a feed gas comprising oxygen, nitrogen and argon while achieving high adsorbent utilization by selective operation of the multi-zone system. The process includes a forward flow stage which comprises (a) passing the feed gas into a first adsorption zone containing an adsorbent selective for the adsorption of nitrogen over oxygen and argon, and withdrawing therefrom a nitrogen-depleted intermediate gas; (b) passing the nitrogen-depleted intermediate gas into a second adsorption zone containing an adsorbent which is selective for the adsorption of nitrogen over argon and selective for the adsorption of argon over oxygen; (c) withdrawing an oxygen- enriched product gas from the second adsorption zone; and (d) terminating the passing of feed gas into the first adsorption zone and withdrawing an oxygen- enriched depressurization gas from the second adsorption zone in the same flow direction as (c). During (a) or during (d), nitrogen breakthrough from the first adsorption zone can occur and nitrogen can be adsorbed in the second adsorption zone. Also disclosed is a multi-zone adsorber for use in such a process.
